Potassium citrate works by passing through the dentinal tubules to the pulp and acting directly on the nerve.Potassium depolarizes the nerve,so it cannot fire and cause pain.Fluoride compounds in toothpastes,gels,or solutions;ferric or potassium oxalate solutions;and chemical solutions containing resin all work by plugging the open ends of the dentin tubules to reduce the fluid movement and stop the pressure on nerve endings.This may be done by a chemical or mechanical blocking process.
